Abstract: Objective To study the prevalence and pathogenic fungi of children superficial mycosis in Wuxi region.Methods Direct microscopy and culture on glucose peptone agar with amphemycin (amphemycin and actinone) were performed and identification was made by morphology.Results Two hundred and forty five in 293 cases (83.6%) showed positive results in direct microscopic examination,including 79 cases of dermatocandidiasis (32.2%),50 cases of tinea pedis (20.4%) and 46 cases of tinea capitis (18.8%).Others involved tinea corporis,onychomycosis,tinea manum,tinea cruris,and pityriasis versicolor which were 29 cases (11.8%),13 cases (5.3%),11 cases (4.5%),10 cases (4.1%) and 7 cases (2.9%) respectively.The incidence was related to the ages of the children.Pityriasis versicolor had the highest incidence in children younger than 2 years old,while oidiomycosis cutis in children younger than 3-year old,tinea capitis between 4 and 8 years old,tinea corporis,tinea cruris and tinea of feet and hands between 9 and 15 years old.Except for 7 cases of pityriasis versicolor,145 strains of pathogenic fungi were cultured successfully from 238 specimen with positive results under microscope (60.9%),among which incidence of cutaneous candida,tinea cruris,tinea corporis,onychomycosis,tinea capitis,ringworm of feet and tinea manus were 70.9%,70%,51.7%,53.8%,65.2%,50% and 45.5% respectively.In all 145 isolates,there were 63 strains (43.45%) of Candida,43 strains (29.7%) of Trichophyton rubrum,26 strains (17.93%) of Microsporum Canis,4 strains (2.76%) of Trichophyton mentagrophytes,3 strains (2.07%) of Trichophyton rubrum Purple,3 strains (2.07%) of Gypsum microspore bacteria,2 strains (1.38%) of Off hairy dermatophytes and 1 strain (0.69%) of Epidermophyton floccosum.Conclusions The study provided the basis for prevention and cure of superficial mycosis of children in Wuxi region.
